UNITED stratus OFFICE MARTIN L. HUN-KER, OF DOVER, OHIO, ASIGNOR TO THEREEVES MANUFACTURING COMLANY, DOVER, OHIO, A CORPORATION OF OHIO norromcons'rnvc'rron Eon cans Application filed December a, 1927. Serial m.asao'zo.

The invention relates to sheet metal cans such as ash cans and the like,and more particularly to a reinforced construction of. such cans, and isan improvement upon the con- 6 struction disclosed in the application ofV. P. Wendle, Serial No. 203,156, filed July 2, 1927, and an applicationof R. J. Curtis Serial No. 232,323, filed November 10, 1927..

As stated in the rior applications, above 10 referred to, it has eencommon practice to rivet a rolled iron hoop around the lower end of thistype of can for the purpose of taking the wear to which such cans aresubjected by being dragged acrosscement floors, and the like, whenfilled with ashes or other heavy material. V

It has also been customary to rivet a similar rolled. iron hoop aroundthe open upper end of such cans to reinforce the same at this point.

The prior applications, above referred to,-

provided for attaching a rolled iron hoop at the bottom of thecan,without the useo'f rivets, thus reducing thelabor and manufacturing costof suchcans.

The ob'ect of the-present improvement is to simpli y and improve suchconstructlons; to make the reinforced structure stronger and moredurable; and torovide a reinforced can which is ada ted or nesting forShlP- ping purposes an the like. i

The above and other objects may be attained by constructing the can inthe manner through the upper and lower portions of the improved can,with the reinforcing hoops insorted there1n',-pr1or to the'finaloperation.

in order that a plurality ofthe cans may be ested together for shippingor storage purillustrated in the accompanying drawing, in

substantially on the Similar numerals refer to similar parts The can ispreferably corrugated longit-udinally, throughout the greater portion ofits body, as illustrated at 5, the corrugations terminating at-the upperand lower end por- -'tions in the outturned substantially horizontalperipheral flanges 6 and 7, respectively.

The body portion of the can, as initiallyformed, is provided with theupturned peripheral flange 8, extending upward from the periphery of'theupper flange 6, and with the downturned, peripheral flange 9, extendingdownward from the periphery of the lower flange 7 the flange t)terminating in the outturned peripheral flange 10.

The bottom 11, of the can, is stamped from a sheet of metal and isinitially formed with the peripheral, upturned flange 12, having theoutturned peripheral flange 13, and depending eripheral flange 14,forming. an upwardly disposed, inverted channel portion. terminating inthe outturned peripheral flangev 15, below the p ane of the bottom 11.

The flange 14 is of suitable height and circumference to fit snuglywithin the flange!) of the body the flange 13, of the bottom, contactinwith the under side of the flange 7, of the ody, while the flange 15, ofthe bottom, contacts with the under side of the flange 10, of the body,in themanner illustrated in Fig.

end portion of the body.

The rolled iron hoop 16 is provided inits peri her with the inclinedgroove 1'], ex-

'tendmgl ownward and inward from the top of the op and terminating atthe substantially horizontal shoulder 18, spaced from the lower edge ofthe hoop.

In assembling the hoop .16, and bottom, upon the body of the can, thebottom} iS-,-l1 1- referably located considerably sorted into the lowerend of the can, as above described, and the hoop is inserted into the xbottom,.as shown in Fig. 1, their per edge of the hoop being locatedbetween t e flanges 12and i l, and contacting with the under side of theflange 13..

By the use of a seamin roller, or the like, the flanges 10 and 15, of te body and bottom respectively, are formed into a double seam 19, andthe flanges 9 and 14, of the body and The entire joint, between the bodyand bottom of the can, is thus received in the inclined, peripheralgroove of the hoop, presenting no exterior obstruction, and permittingthe can to be easily inserted within a similar can, thus providing fornesting of the cans for shippin or storing the same.

It wi 1 be obvious, from an inspection of Fig. 2, that the flanges 9 and14, when pressed into the inclined groove of the hoop, are tapered at agreater angle than the body por tion of the can, thus securely lockingthe hoop in position at the lower end of the can.

The upper hoop is adapted to be received within the upstanding flange 8,at the upper end of the can, and to rest upon the flange 6 thereof. Theinternal groove or reduced portion 21 is formed at the upperend por- 7tion of this hoop.

With the hoop in place, as shown in Fig. 1, the. free, upper portion ofthe flange 8 is then pressed or formed over the upper edge of the hoop,and down upon the inner side there0f,seating in the groove 21 of thehoop, as shown in Fig. 2. p

Therolled hoops are thus attached to the upper and lower ends of the canwithout the expense and labor of riveting the same, andv it will bevseen that these hoops are firmlyand rigidly held in place, with thelower hoop extending below the bottom or the can,

so that only the hoop contacts with the cor or ground, whereby all ofthe wear caused by sliding upon the floor is received by the hoop,preventing rapid wear of the bottom of the can.

and the hoops may be easily and quickly assembled upon the can, in asimple operation.

I claim: 1. A sheet metal can comprising a body portion having anoutturned, substantially horizontal, annular flange at its lowerportion, terminating in a downturned peripheral flange, a bottom havinga peripheral, 11 wardly disposed, inverted channel portim a apted to bereceived within the lower end portion of the. body and to contact withsaid Y outturned flange, the-inner side of the an nula-r channel portionof the bottom being flush with the inner wall of the body, and a hooplocated within the annular channel portion of the bottom and having atapered peripheral groove into which'the lower end portion of the bodyand-the termination of the channel portion are adapted to be pressed. 2.A sheet metal can comprising a body portion having-an outturned,substantially f horizontal, annular flangeat its lower por-
